I won't get back to Beijing for at least a month.
1 get back 和 go back有什么区别?
2 at least a month 前面为什么要加一个介词for? 不是已经有at了吗?
在这里没有什么区别，都是返回，一段时间或者空间距离前常用介词for。at和least是组合，表示最低要求或者程度。

两者的用法有个最大区别在于常用和误用：
常用 I won't go back to Beijing for at least a month.
误用I won't get back to Beijing for at least a month.
正确get to, I won't get "back Beijing"(名词) until
one month at least.
常用 I won't go back to Beijing for at least a month.
误用I won't get back to Beijing for at least a month.
正确get to, I won't get "back Beijing"(名词) until
one month at least.

感觉上，get back 比 go back 更加肯定。用中文表述可以是：我至少一个月回不了北京，我至少一个月不想回北京。
